Also note this; On my system, I have these GRUB entries; (hd0) = 1st *system* Harddisk (hd1) = 2nd *system* Harddisk, but located at (SM) Secondary Master (which is the 3rd IDE position). Most are aware of this - but I recently noticed that my 2nd HD is on hd*c*, yet I would've assumed that BRUBwould assign that as hd2 - since it's the 3rd IDE device (the 2nd IDE device, hdb, is an ATAPI CD Drive). So, using an older Intel Mobo, PII, a typical IDE setup, I have PM = (hd0,0) = 1st Harddisk, 1st partition PS = CDRW = nothing for GRUB SM = (hd1,0) = 2nd Harddisk, 1st partition SS = DVDRW = nothing for grub Note that SM is the 3rd IDE device...yet GRUB sees it as the 2nd. IOW - my one (likely unnecessary) small point is; GRUB doesn't count ALL the IDE devices when assigning it's 0,1,2,3 - only Fixed Disks are noticed/seen...(likely something to do with the int13 extensions that IDE Harddisks use, but that's just a guess at best).
